The coorchnated systems (Cu(II)-neutral L-lsoleucme and Cu(II)-L-lsoleuanate Ion have been sturhed polarographlcally, m aqueous medmm, p=l OM (NaClO,) and 25kO l"C, and the stability constants of the complexes ICuI1'+ (/311, =23), ICuI,1'+ (&= 180) and JCu(I-),I (jloz= 1 8 10") have been determined

The minimum presented by the polarograms of the reduction of Cu(I1) in Li+, Na+ and K+ citrate is analysed in order to determine the charge of the reacting species and the coefficient of transfer, OL, of the process. The results obtained allow the participation of thecomplex anions (Cu,Cit,)'-and (C
